Tough one:
That's a tough one. I suppose if the massagetherapist over extended your neck backward and you had some decreased flow to the brain due to narrowed arteries, you might pass out. Otherwise I cannot think of another good reason.

Continuum:
Coma is the deepest form of loss of consciousness (loc), in which no responsiveness to the external environment exists. This can be reversible. Technically a concussion with loc means a momentary coma has occurred but the term is rarely used in that circumstance. Simple loc means loss of awareness to some external stimuli with preserved responsiveness to noxious stimuli.

Can't decide:
Both can be life threatening; loss of consciousness during choking is a progression nearer to death. Loss of consciousness can ocurr in many cases and reasons and is always serious.

Lost consciousness:
If you had real loss of consciousness then I hope you are under the care of a physician. If you had more than one episode of sudden loss of consciousness then you need a full work up. Are those caused by seizures, or by a cardiac arrhythmia, aortic stenosis or tias, medication effect, or just fear. Get a neurologist & cardiac evaluation or at least go to your pcp.

Yes:
Yes it can, you may not "pass out" but you will not remember the event. In children these are called "petit mal" seizures or absence seizure. They may appear as staring spells, hence the name.

Depends:
Seizures can be partial or generalized. These categories mean either without or with loss of consciousness. It is important to note a seizure can be very short in duration so the loss of consciousness may be so brief and one is often sleep or fatigued following a seizure so that may be perceived as an alteration of consciousness.

No:
You can have convulsions and not lose consciousness if the seizure phenomenon causing the convulsions doesn't spread to an area of the brain altering consciousness. Are you being treated?

Not likely:
The brain is well cushioned in a pool of fluid surrounded by a tough bony shell. A heat hit with no loss of consciousnes and a lack of the dazing (called by coaches ringing your bell), is unlikely to have any demonstrable effects. Of course I assume this is isolated and you are not having repeated blows to the head. This is why athletes wear helmets.

Usually immediate:
Most times loss of consciousness is immediate. A delay of minutes to hours would be a cause for alarm and an immediate visit to the emergency room as an internal bleed in the head would need to be ruled out. Usually someone is knocked out (right away) for seconds to minutes and that in itself warrants and er visit. Any loss of consciousness basically needs to be evaluated in the emergency room.

Up to 2 years:
Traumatic brain injury (concussion falls into this category) are notoriously slow to heal taking months or even years to fully improve. In some cases the resultant symptoms can be permanent especially if the injuries happen repetitively (think football).

Go see your doctor:
I'm glad to hear your MRI & eeg were negative 11yrs ago but you need a complete evaluation for this new episode. Any witnesses to your passing out? Could be from low blood pressure due to anemia or dehydration. Could be an abnormal heart rhythm. Could also be seizure of some sort. Go see your doc to get checked out. Not to be rude but speculation online isn't going to do you any good.

Way off the mark:
You are focused on totally the wrong thing. Hasn't it occurred to you to be concerned about your son's episode?? It sounds like a seizure to me. Forget about cancer, that's irrelevant, and get the kid evaluated for epilepsy.

We all are:
We all are at a small risk of cancer. That's because all humans get cell mutations, but fortunately our risk of cancer is small until we get to an older age. A baby's risk of cancer does not change when he gets several typical x-rays. That being said, one should only do x-rays when needed for a medical purpose.

Probably not:
Ct is useful in the acute setting to look for bleeding or fractures. Several months after your accident, it is very unlikely that ct would be helpful if you are not having any new symptoms. If there is any subtle abnormality due to your accident at this point, it is more likely to be seen with mri, but again this is not necessary unless you are having new symptoms.

Consciousness:
Loss of consciousness indicates the need for you to go to your emergency room right now. Once your medical situation is clarified you need to see a mental health professional for the treatment of your anxiety, depression, and paranoia. Peace and good health.

Uncommon in young:
Most subdural hematomas occur in patients over the age of 60 years. The vast majority of patients who have an acute subdural hematoma present with loss of consciousness. Younger patients often have a history of alcoholism, arachnoid cysts, thrombocytopenia, or a bleeding tendency. Radiographic imaging is diagnostic.

Concussions syptoms:
Take months to clear in many cases. Multiple concussions cause more difficulty than one. It is important to be monitored by your doc. Loss of consciousness is not necessary. Peace and good health.

Urgent evaluation:
A blown pupil following trauma could be from orbital injury, but, much more worrisome, would be something compressing on the responsible nerve in the brain, such as from brain swelling. This needs to be checked out immediately.

Not likely:
Healthy 22 yr usually has a pretty hard-head. It has been 12 hours and you don't really have any concerning symptoms and so significant brain injury is highly highly unlikely. If u were 72 it would be a different story because of a possibility of a very slow bleed. So, just be careful playing sports/protect your head, otherwise you are lucky this episode. Good luck.

Yes, Doc ASAP:
Severe and widespread poison ivy reactions may be nearly as bad as having a 3rd degree burn making you susceptible to infection. You need to be properly hydrated and treated. See a doctor ASAP. Be sure that all items potentially exposed be cleaned with a laundry detergent (wear glove if you are doing it) to avoid further exposure to the resin.

Syncopal episode:
You need some work up to find the cause. Go to an urgent care or ER if you can not get a hold of your doctor by phone. The treatment is according to the cause. Check this link.http://www. Merckmanuals. Com/home/heart-and-blood-vessel-disorders/symptoms-of-heart-and-blood-vessel-disorders/fainting

Sounds like you might have had a seizure. Please tell me that you went to the emergency department to be evaluated. You should be. You need a neurological exam and likely an MRI of both your neck (to rule out ligament injury) and brain.
